Skiplist

A generic Skiplist container C implementation, lock-free for both multiple readers and writers. It can be used as a set or a map, containing any type of data.

It basically uses STL atomic variables with C++ compiler, but they can be switched to built-in GCC atomic operations when we compile it with pure C compiler.

This repository also includes STL-style lock-free set and map containers, based on Skiplist implementation.

Build

$ make

How to use

Copy skiplist.cc file and include files to your source repository.

Or, use library file (libskiplist.so or libskiplist.a).

  • Pure C

examples/pure_c_example.c

  • C++ (STL-style set and map)

examples/cpp_set_example.cc

examples/cpp_map_example.cc

Benchmark results

  • Skiplist vs. STL set + STL mutex
  • Single writer and multiple readers
  • Randomly insert and read 100K integers
